Farklı Dolgu Duvar Malzemesine Sahip Binaların Deprem Davranışının İncelenmesi

Binalarda yapı malzemesi olarak farklı yığma malzemeler yaygın olarak kullanılmaktadır. Betonarme yapıların deprem etkisi altındaki mevcut durumu incelendiğinde, betonarme yapılarda kullanılan malzemelerin özelliklerine bağlı olarak betonarme yapıların davranışlarında farklılıklar olduğu görülmektedir. Deprem etkisinde betonarme yapıların mevcut durumu incelediğinde betonarme yapıların kullanılan malzemelerin özelliklerine göre yapı davranışında farklılıklar meydana gelmiştir. Bu durumun sebebi tercihe dilen malzemenin fiziksel özellikleriyle ilişkilidir. Betonarme yapıların çerçeve sistemi dolgu duvarlarla tamamlanmaktır. Türkiye’de inşaa edilen betonarme yapılarda dolgu duvarlarda gazbeton ve tuğla malzemeler kullanılmıştır. Bu çalışmada, dolgu duvarlı betonarme yapıların deprem etkileri altındaki mevcut durumunu analiz etmek için sonlu elemanlar programı kullanılmıştır. SAP2000 sonlu elemanlar programı kullanılarak betonarme çerçeveli bir yapı modeli tasarlanmış, model yapısında iki farklı malzeme tercih edilmiş ve dört farklı model kombinasyonu tasarlanmıştır. İlk iki model dolgu duvarlı olarak tasarlanmıştır ancak zemin kat ve diğer modeller tüm bina için dolgu duvarlı olarak tasarlanmıştır. Doğrusal olmayan statik itme analizleri yapılarak taban kesme, deplasman ve kat öteleme değerleri elde edilmiştir. Sonuç olarak tüm sonuçlar grafiklerle sunulmuştur. deprem etkisi altında birim hacim ağırlığı düşükolan gaz beton malzemeli modelden elde edilen verilerin tuğla malzemeli modele göre daha sağlıklı olduğu tespit edilmiştir.

Investigation of Seismic Behavior of Buildings With Different Infill Wall Materials

Different masonry materials are commonly used construction materials for buildings. When the current situation of reinforced concrete structures under earthquake effect is examined, it is seen that there are differences in the behavior of the reinforced concrete structures depending on the properties of the materials that are used in the reinforced concrete structures. The reason for this situation is related to the physical properties of the preferred material. The frame systems of reinforced concrete structures are completed with infill walls. Aerated autoclaved concrete and conventional brick materials are used as infill wall materials in most of the reinforced concrete structures built in Turkey. In this paper, the finite element program was used to analyze the current state of reinforced concrete structures with infilled walls under the earthquake effects. A reinforced concrete framed structure model was designed using the SAP2000 finite element program, two different materials were preferred in the model structure and four different model combinations were designed. The first two models are designed with infill walls, but the ground floor and the other models are designed with infill walls for the whole building. Nonlinear static pushover analyses were conducted, and base shear, displacement, and story drift values were obtained. As a result, all the results were presented by graphics. the data obtained from the model with Aerated autoclaved concrete material, which has a low unit volume weight under the effect of the earthquake, is healthier than the model with conventional brick material.
